Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient.

Sodium ion moving against the concentration gradient requires active transport.
What is active transport?
Active transport is the energetically-intensive movement of molecules across a membrane against a concentration gradient from an area of lower concentration to a region of greater concentration.
What is the difference between active and passive transport?
- Active transport moves molecules against the concentration gradient by using energy.
- Passive transport moves molecules along the concentration gradient without using energy.
What are the types of active transport?
The types of active transport are:
- Adenosine triphosphate (ATP)-based primary active transport
- electrochemical gradient-based secondary active transport
